Abstract
In this paper, a model-independent adaptive PID control scheme is proposed for the angle control of electromagnetic scanning micromirrors. In this scheme, only using the input and output data of the micromirror, a model-free adaptive mechanism is designed to adjust the PID parameters online to adapt to the change of the micromirror characteristics due to the hysteresis exists in the micromirror. It makes the deflection angle of the micromirror can track the reference trajectory fast and accurately. Finally, the simulation results show that the proposed control method has achieved better control performance than PID control in controlling the deflection angle of the micromirror.
